<p><b>Perfect Developer</b> (PD) is a tool for developing <a href="Computer_programs" class="mw-redirect" title="Computer programs">computer programs</a> in a rigorous manner. It is used to develop applications in areas including IT systems and airborne critical systems. The principle is to develop a formal specification and refine the specification to code. Even though the tool is founded on <a href="Formal_methods" title="Formal methods">formal methods</a>, the suppliers claim that advanced mathematical knowledge is not a prerequisite.
</p><p>PD supports the Verified Design by Contract paradigm, which is an extension of <a href="Design_by_contract" title="Design by contract">Design by contract</a>. In Verified Design by Contract, the contracts are verified by <a href="Static_analysis" title="Static analysis">static analysis</a> and automated theorem proving, so that it is certain that they will not fail at runtime.
</p><p>The <b>Perfect</b> <a href="Specification_language" title="Specification language">specification language</a> used has an <a href="Object-oriented_programming" title="Object-oriented programming">object-oriented</a> style, producing code in <a href="Programming_languages" class="mw-redirect" title="Programming languages">programming languages</a> including <a href="Java_(programming_language)" title="Java (programming language)">Java</a>, <a href="C_Sharp_(programming_language)" title="C Sharp (programming language)">C#</a> and <a href="C%2B%2B" title="C++">C++</a>. It has been developed by the <a href="United_Kingdom" title="United Kingdom">UK</a> company <i>Escher Technologies Ltd</i>. They note on their website that their claim is not that the language itself is perfect, but that it can be used to produce code which perfectly implements a precise specification.
